l shallwbe"ofi-improved construction and op-V eration.

` The invention is exemplified in the combmation and arrangements of parts shown in the accompanying drawing and described in the following specification and in the i stepsof the process described therein. The invention is Vmore particularly pointed out the appended claims. In the drawing- 4Figure 1 is an elevational view of a bullet g of the kind to which the present invention 1 isapplied.

Figa` 2 is a longitudinal sectional view of Usuch a bullet, and

c Fig 3 is a longitudinal sectional view showing the parts of the bullet separated and arranged in the order in which they are assembled. i

3: In the `construction ofnietal j acketed bull` i `lets, for high power rilies it is desirable that I j a bullet shall be comparatively long in order j to give "as long a bearing as possible inthe barrel of the rifle to produce accurate results in firing. It has Vbeen found that if a bullet `is made of suiiicientlength for accuracy andthe jacket entirely `filled with l lead the bursting strain of the gas pressure in the riiie becomes excessive. [.the same `dimensions but of less weight re- A bullet of i uires less O'as ressure for the same range pcf fire and hence it is desirable to reduce @fthe weight of the bullet.

j This result is accomplished in the present invention. by

leaving the forward portion of the jacket hollow and filling only the rear portion with@ lead,` as indicatedin Fig. 2 of the drawing.

l" Theyhollow portion is located at the forward end of the bullet in order to bring the, center 1` `of gravity of the bullet near the base thereof as this arrangement produces a steadier `iiight lthanany other distribution of weight. In manufacturing abullet of this character an integral hollow jacket like that shown at JACKETED ELLET.

10in`Fig. 3 is constructed in the usual manner.- `It is usual to form this jacket of cupro nickel, but theparticular material used for the jacket constitutesno, part of the present Y Y invention. A cup-shaped abutment l1 taperedto t within thepointed end of the jacket and made of thin sheet metal is in- 12 is in place the rear portion of the jacket 10 is turned over, as shown at 14 in Fig. 2, to form an inwardly projecting ledge to `hold the parts of the bullet in place. The

. bullet is then connected with the shell in the usual manner and is ready to use.

I claim:

`1. A bullet comprising a jacket having a hollow space therein, said hollow space eX- tending to the inner wall of the jacket, lling material within the bullet, and a sheet metal abutment separating the hollow portion of the bullet from the space occupied by the filling material.

2. A bullet comprising an outer jacket, a cup-shaped abutment positioned within said jacket and having its open end extended toward the front of the bullet, and filling material located within said jacket in the rear of said abutment.

3. In combination, a jacketed bullet having an open space in the point thereof eX- tending to the interior wall of the jacket,

and having filling material within said jacket and an abutment located between said material and said open space, said abutment having a hollow interior communicating at its forward end with said open space. j '4.' In combination, a bullet comprising a metal jacket having an open space at the forward end thereof, filling material within said jacket at the rear of said open space, and an abutment member between said open space and said filling material, said abutment memberhaving a hollow interior and a rear abutment wall integral with said member.
